Cochin China, and described and figured by Is. Geoffroy as M. 

 arctoides. 



2. Along with the examples of Macacus arctoides Mr. Jamrach 

 brought a single male specimen of another closely allied, but ap- 

 parently distinct, species of Macaque, which he obtained in the Cal- 

 cutta market. Having the same general structure and short tail as 

 M. brunneus, it differs in the general reddish colour of its fur. For 

 this animal I adopt the temporary name {Macacus rufescens) sug- 

 gested by Dr. Anderson {anted, p. 204). I hope hereafter to be 

 able to give a complete account of it. Meanwhile the accompanying 

 figure (Plate XXIV.) will render it easily recognizable. 



3. Mr. Jamrach also brought from Calcutta a single female speci- 

 men of a third Macaque, likewise apparently distinct from any other 

 known species. On this species (Plate XXV.) I have conferred the 

 the temporary designation Macacus rheso-similis. It is most nearly 

 allied to M. rhesus and M. radiatus ; and Mr. BIyth has suggested 

 to me that it may even be a hybrid between those species. 



4. Another prize secured by Mr. Jamrach in Calcutta, and obtained 

 from him on the same date, is a fine adult specimen of the Double- 

 wattled Cassowary (Casuarius bicaruncidatus). 



I first established this species in 1860, on an immature specimen 

 living in the Society's Gardens *. A second, likewise immature ex- 

 ample was obtained in 1869 t, but, like the former, unfortunately died 

 before attaining the adult stage. 



The specimen now obtained is of the highest interest, as showing 

 how very distinct this Cassowary is from all its congeners. Referring 

 to the arrangement of the genus which I gave in my last notice on 

 this subject (see P. Z. S. 1872, p. 150) Casuarius bicanmculatus 

 belongs to the group with the compressed casque, containing C. gale- 

 atus and its allies, and is more nearly allied perhaps to C. galeatus 

 than to any other known species, but, putting aside the obvious 

 distinction of the two lateral widely separated neck-wattles, may be 

 at once distinguished, as will be seen by the accompanying figure 

 (Plate XXVI.), by the smaller casque which rises from a much 

 smaller basis on the vertex, and by the very different colouring of 

 the head and neck. 



5. A female Prongbuck {Antilocapra americana) purchased from 

 a dealer in Liverpool on the 21st of February. 



The only individual of this species hitherto ever possessed by the 

 Society is the male received in 18651, upon which Mr. Bartlett's 

 observations upon the shedding of its horns and Dr. Murie's notes 

 upon the anatomy of this animal were based §. A male example of 

 this animal was subsequently received by the Zoological Gardens of 

 Antwerp, but has since died. So far as I know, our present specimen
